Thanks Laurent. You obviously know a LOT more about SELinux than I. I
pretty much just use commands and not build policies. So I need some
more information here.
From what you provided below, how do I determine what is currently in
place and how do I add your stuff (changing postgresql with mysql, nat.)
thanks
Quick’n’(really) dirty SELinux howto:
1) Run the service. fails due to missing selinux policy.
2) grep service_pattern /var/log/audit/audit.log | audit2allow -M
myservice_policy
Do you really mean 'service_pattern', or is this a placeholder for
something like mysql?
As I get 'Nothing to do'
placeholder which changes according to your needs.
I just made it worst. I put in mysql for myservice_policy, got a /pp
and did:
semodule -i myservice_policy.pp
Now I get real errors like:
